SPECIFICATION forming part of Letters Iatent N o. 661,662, dated November 13, 1900.

Application filed August 22, 1899. serial No. 728,098. (No model.)

To all whom, it may concer-71,:

Be it known that I, GUsTAv KoRYTowsKI, a subject of the German Emperor, residing at Leipsic, in the Empire of Germany, have invented certain new and useful Improvements in Devices for Changing the Tracers of Sound-Reproducing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

My present invention has reference to talking-machines.

The reproducers in gramophones, phonographs, and the like are usually providedwith a needle or its equivalent which follows the engraved lines of the record, and the needles being generally of soft metal are liable to wear, the wear being in some of the apparatus, especially in gramophones,l a rapid one, thus necessitating frequent changing. This has heretofore been generally done by hand, but owing to the delicate mechanism of the reproducer a certain skill is required for inserting and fixing the needles, which obviously cannot be done by every one.

The object of this invention is to provide a means for automatically discarding the used needle and simultaneously replacing it with a freshone.

To this end the invention consists in a magazine for carrying a plurality of needles, a needle-holder to which the needles are fed, a means for feeding the needles to said needleholder, and in certain details of construction, all as lhereinafter described and claimed.

In order to more fully describe and ascertain the nature of the said invention, reference will be had to the accompanying drawings, which illustrate a preferred embodiment of my invention, and wherein- Eigure lis a face View showing the general arrangement. Fig. 2 is a longitudinal section of Fig. l, and Fig. 3 represents details showing a transverse section through the magazine and a modification of the needle-holder.

The invention is shown as applied to a reproducer of the Berliner system.

a designates the sound-box, having diaphragm b, retained by disk c in the usual manner. The sound-box is provided with a .other suitable means.

lateral recess, in which is mounted the needle-holder support d, secured by a screw or The needle-holder e may consist of a tubular member integral with the support or may be tapered and split longitudinally at its forward end, as shown at e in Fig. 3, so as to assume the function of a clamp to prevent the operating-needle from being displaced.

The needle-holder is provided with a setscrew f, the head of which is formed as a pinion g, carrying a pin g', which prevents the screw from being fully rotated by bearing against a spring h, retained by screw h on the sound-box.

t' designates the stylus connecting the needle-holder support d and diaphragm I) in the usual manner.

The magazine j is preferably constructed of sheet metal and consists of a rectangular member having a sight-opening extending the length thereof. The needles are loosely received therein and superposed one upon the other, as shown at with their points facing the needle-holder.

The magazine may be secured to the soundbox in any suitable manner. In the present instance I have shown it as being received at its base in a boX or trough n, mounted in a support upon the sound-box. This magazine is provided with a grooved shoulder j', in which is adapted to engage a spring-wire 7c, mounted in a segmental plate lo', secured to the sound-box. The magazine has a pusher or tensioning device for the needles, which comprises a presser-block Z, having its under side inclined to coincide with the tapered form of the needles and having a shank Z eX- tending through the sight opening, upon which is adapted to bear one arm of a spring m, the other arm of the spring being retained in plate 7c'. r

Any suitable means may be employed for feeding the needles to the needle-holder. In the present instance I have shown a box or trough n, into which the magazine feeds, said box being axially alined with the needleholder and provided with a lateral opening closed by a reed or spring n', having an inwardly-protruding pin n2, adapted to bear upon the tapered point of the second needle to prevent the same from creeping forward against the operating-needle. Said trough n is integral with or otherwise mounted upon a support o, retained by screws 0 upon the sound-box. The support 0 has a tubular extension or sleeve p, provided at. its outer end with a flange p', having an eye p2. (Shown dotted in Figs. 1 and 2.) A plunger or rod q is guided centrally of said sleeve to be in axial alinement with the needle in trough n and is threaded, as at q', to be received in a cylindrical block r, having a flange r. A coil-springs is mounted upon said block and ilnpinges at its ends against the flanges p and r', normally tending to keep the rod q retracted. The flange r has rigidly connected therewith a rod t, guided in the eye p2 and in a guide u, secured to the support o. The rod tcarries at its other end a rack n, attached thereto in any suitable manner and adapted to engage the teeth of pinion g when the rod q is actuated. The magazine being supplied with needles, the lowermost one will lie in the trough n, and it will be seen that by depressor departing from the spirit of my invention. p'

Having thus described my invention, I claiml. A reproducer for talking-machines having a plurality of reproducing-needles ina substantially common plane and automatic means for discarding the used needle and simultaneously replacing it with` a fresh one.

2. In a reproducer for talking-machines, a magazine containing a number of reproducing-needles arranged in a substantially common plane, and means for putting said needles into position, one afteranother, to reproduce sound. l

3. In a reproducer for talking-machines, a magazine, a number of reproducing-needles in superposed relation, and automatic means for simultaneously ejecting the used needle and replacing it with a fresh one.

4. In a reproducer for talking-machines, a magazine containing a number of reproducing-needles in superposed relation and having adownward feed, and automatic means for simultaneously ejecting the used needle and replacing it with a fresh one.
